Evaluation of closed and open intramedullary pinning for repair of tibial fractures in dogs

Repair of tibial fractures was done by single intramedullary pinning through open surgical technique (n=5) in group I and by using closed technique under C-arm image intensifier (n=5) in group II. The mean alkaline phosphatase, creatine kinase and calcium values decreased on day 15 and increased on day 30 in group I but they gradually increased till day 30 in group II. The mean phosphorus level decreased significantly at day 15 in group I but it increased significantly at day 15 in group II. Complete radiographic callus could be observed at day 45 in group I and day 30 in group II. Closed method of IM fixation for tibia fracture repair was found to be a better technique in terms of early return of limb function, shorter duration of surgery and earlier healing.
